Missing RAM problem

I have a Ryzen 5950x with 32GB and 64GB. In both cases, Ubuntu is reporting 2-3GB less. BIOS is up to date.

It would be great to claim those 2-3GB memory back and put them to a good use. The CPU does not have integrated graphics.

On my Laptop (Acer ES1-562-5191) I have an Intel Core i5-7200U which normally runs at 2.50GHz. I have turbo boost enabled and it works. Everything is fine except for the fact that at a certain power level (around 15%) Turbo Boost gets disabled. It doesn't get re-enabled after charging the laptop. The only way to fix this is to restart the laptop.

Keyboard Logitech K380 not detected
us flag

Tuxedo laptop with Ubuntu 18.04. I tried to connect my K380 (which used to work with Ubuntu 20) using blueman. Initially the keyboard was listed among the devices but although I was able to pair it, it was not working. I then deleted it from the list and now it's not detectable anymore. Even with bluetoothctl, the device is not listed. What can I do?

I am experiencing the exact same situation as described in this query KMail stops working after install of MySQL I have not seen a resolution anywhere. Does this mean that the only way forward is to move up to Ubuntu 21.04?

I uninstalled the new mysql server and reinstalled akonadi-server and akonadi-backend-mysql. Did not help. Is there a known issue with akonadi on Ubuntu 20.04.2?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
